SOI stands for “Structure of Intellect,” which is the proven theory that intellectual abilities can be both identified and improved. SOI is an exciting, beneficial way of approaching intelligence, learning, and education!

We focus at the very root of learning. Successful learning requires a certain level of different abilities to be in place – comprehension, problem solving, evaluation, memory, etc.

Our tests, products, and programs all work together to ensure that these abilities are exactly where they need to be so that you, your child, or your students can unlock your full learning potential!

WE WORK CLOSELY WITH OUR SCHOOLS, PARENTS, AND PRACTITIONERS TO ENSURE LEARNING SUCCESS THROUGH THE USE OF SOI MATERIALS & PROGRAMS.

managed programs that provide students with the very best educational foundation

innovative programs designed specifically to assist struggling students to get them back on track

tests that profile learning ability strengths and weaknesses

identification of learning style

materials to improve and strengthen learning abilities

career recommendations

four unique levels of training

trained in SOI test administration and interpretation

THE HISTORY OF SOI

We love sharing our story! It starts back during World War II when about 35% of pilots were failing out of the Air Corps. These men had IQs over 120, but they still weren’t making it.

It became Dr. J.P. Guilford’s job to find a new way of measuring intelligence. Guilford drew up sets of intellectual functions required for the various Army Corps jobs, and constructed tests that measured those abilities.

Guildford’s tests were used to select personnel with the most intellectual potential for training, and the washout rate dropped by more than 25 percent!

Pleased with Guilford’s great success, the Defense Department funded Guilford for the next twenty years in the Aptitudes Project at the University of Southern California.

He and his students continued to identify many different abilities, and a model began to take shape. That model became the Structure of Intellect.

Dr. Meeker’s most exciting and important contribution was her realization that intellectual abilities could be taught! This added a whole new dimension to Guilford’s work. At this point, not only could abilities be identified, but they could be taught and developed, too! This coupling is what makes SOI unique. It provides the basis of all our tests, products, and programs that have been developed by Dr. Meeker and her husband, Dr. Robert Meeker.

SOI Systems was officially founded in 1965. And here we are today, more than 50 years later, continuing to impact lives and make a difference, all thanks to the research and development of such a powerful learning system!
